WIDI MP3 MIDI Converter is a three in one convertor (wav to midi,mp3 to midi,cda files to midi converter) for live performance, making MIDI files, transcribing music, and also can converting midi sequence from polyphonic WAVE and MP3 files(having many tones or voices) and CDs.

It designed to automate transcribing of music. That means that the task of retrieving music score from an audio record, which is usually accomplished by a hard work of a professional musicians,is about to be solvable by a computer. You can take you favorite audio record and convert it into notes.

It can work both in real-time and off-line mode. In off-line mode WIDI creates MIDI sequences from input files (like mp3s or audio CD tracks).

in real-time mode, instantly converting music at the microphone or line input of your computer into a MIDI sequence. Think of this mode as a powerful music processor which allows some non-MIDI instrument (like a guitar) to sound as a violin or a piano or whatever instrument you've got in your MIDI synthesizer.

- pitches to transcribe are selectable
- subject to tuning
- algorithm selection.
- minimal duration of notes (wrong short notes can be cut off).
- number of voices.
- time resolution (usually higher than minimal note duration).
- length of input file is not limited.
- does not differentiate instruments in source file, but allows you to use any instrument in the output MIDI file.

how this program works

Every musical note has pitch, which corresponds to the frequency of main tone. Modern musical scale has almost 100 pitches with frequencies from approximately 30 hertz to 4,5 kilohertz. Neighbor notes frequencies (C and C#, E and F) are always related as 2 in 1/12 power, so notes making an octave interval (=12 smallest called semitones) have frequencies rated as 1:2. There are other scales too, but they are rarely used.

User Review

"Pretty courageous!"
My mind was blown when I saw that you were offering software that could take a wave file and convert it to a midi file. I downloaded it and saw that it could actually shorten the process of transcription by providing a matrix from which to work! You've got game! I had no idea the technology was even close to being possible. -- Phil Christensen
